Even when pressing the power button, the printer does not respond.

If the printer is plugged into a surge protector or power bar, try plugging it directly to the wall. If it is not, try switching it to a different outlet.

In some cases, your printer may have a faulty AC Power Adapter. In this case, you can replace your AC Power Adapter.

You are unable to print wirelessly from a computer or smartphone.

In order to print, your computer or smartphone must be connected to the same network as the printer. If you have multiple networks in your home or office, check to make sure you are on the same network as your printer.

To change the network on your printer:

1. On the touch screen, press the Wireless icon, then press the Wireless Menu icon (shaped like a gear).
2. Press Wireless Settings, then Wireless Setup Wizard.
3. Select the network you would like to connect to, then follow the on-screen instructions

In certain cases, your network may not allow wireless printing. Try contacting your service provider if you believe this may be the case.

The printer screen or your computer displays "There is a problem with the printhead."

A software problem may be causing this issue. A hard reset may solve your problem. To perform a hard reset:

1. Power on the printer
2. Remove the power cable from the back of the printer
3. Wait 60 seconds
4. Plug in and power on the printer

2. Press Printer Maintenance
3. Press Clean Printhead. There are three cleaning stages and between each a test page will be printed.
4. Examine the test page for print quality
   • If the print quality is still poor, press Proceed to continue to the next level of cleaning. Repeat this process on each step if necessary.
   • If the print quality is normal, press Done.

You can use an automated service to align the printhead. To do this:

1. Press the Setup icon
2. Press Printer Maintenance
3. Press Align Printhead
